Rail Projects Victoria (RPV) is an agency of the Government of Victoria, Australia, responsible for the management of certain major infrastructure projects on the Victorian rail network. Originally established as the Melbourne Metro Rail Authority (MMRA), to deliver the Melbourne Metro Rail Project, the office was later expanded in its responsibilities to include the management and planning of a number of major infrastructure programs on V/Line's regional rail services. It was renamed RPV in 2018 to reflect its expanded scope, and later became one of several project teams comprising the Department of Transport's Major Transport Infrastructure Authority.
